Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterAir Duct Cleaning Company in Covina, CA
Air duct cleaning in Covina typically runs $350 – $650 for a whole-home system, with dryer vent cleaning adding $120 – $180 and duct sealing ranging $800 – $1,500 depending on attic accessibility. We dispatch crews from our Los Angeles office and serve Covina homes with the same equipment we’d use on a commercial job: Rotobrush rotary systems, Nikro negative-air machines, and filtration hardware from Honeywell and Aprilaire. Covina’s combination of 1950s-70s tract housing, freeway-proximity dust, and Santa Ana wind events means duct systems here accumulate a grittier, more abrasive debris load than inland neighbors. Call (361) 326-5060 for a written estimate before any work starts.
Why Covina Homes Are Different
Covina sits in the San Gabriel Valley downwind of the 57/10 freeway corridors and the Santa Ana winds, so duct systems here collect a distinctly gritty mix of brake and tire dust, freeway diesel soot, and seasonal windblown San Gabriel Valley dust that inland-coastal neighbors like West Covina or Glendora don’t get in the same combination. That, layered over a housing stock of 1950s-60s postwar tract homes with original or poorly retrofitted ductwork, is what makes Covina duct cleaning its own job.
Much of Covina’s core is single-story ranch housing built during the post-WWII San Gabriel Valley boom, typically with low-pitch attics and original or once-retrofitted sheet-metal and flex duct runs. Many of these homes have had HVAC replacements but kept the original duct layout, so we routinely find disconnected flex runs, crushed attic ducts, and floor-register boots that no longer seal. The hot, dry inland summers push AC systems near-continuously from June through September, recirculating dust and allergens for months; fall Santa Ana events then dump additional fine dust and wildfire ash into attic and outdoor returns. Attic ducts in these older ranch homes often bake through 100°F-plus summer attic temperatures, drying out and cracking flex duct insulation and mastic seals. By the time a homeowner smells that dusty attic odor when the AC kicks on, the duct is usually leaking into the attic, not just dirty.
Our Main Covina Services
These are the three jobs Covina homeowners call us about most often. Each has its own page with full pricing, process details, and neighborhood-specific notes.
Air Duct Cleaning in Covina
We clean the full supply and return network using a Rotobrush rotary brush system for the main trunk lines and branch ducts, paired with a Nikro negative-air machine to pull loosened debris out of the system rather than pushing it back into your home. In Covina’s older ranch homes, we pay particular attention to crushed flex runs in low-pitch attics and disconnected boots behind floor registers. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Covina has full details.
Dryer Vent Cleaning in Covina
Dryer vent cleaning in Covina runs $120 – $180 for a standard single-story ranch with roof or wall termination. We use rotary brush systems and high-velocity air to clear lint buildup from the dryer connection through the termination point. Covina’s older homes often have longer vent runs through low attics or crawl spaces that sag and trap moisture, accelerating lint accumulation. We inspect the full run and note any crushed or disconnected sections. Dryer Vent Cleaning in Covina covers pricing and scheduling.
Duct Sealing in Covina
Duct sealing in Covina addresses the cracked mastic, dried flex insulation, and separated joints we find in postwar ranch attics. We apply duct sealing mastic and mechanical fasteners to restore the pressure boundary, then verify with a smoke pencil or pressure test. Typical Covina jobs run $800 – $1,500 depending on attic accessibility and linear footage of accessible duct. Sealing is often the right follow-up to cleaning in these homes, since the same age and heat exposure caused both the debris accumulation and the leakage. Duct Sealing in Covina has the full breakdown.

FAQs About Air Duct Cleaning Company in Covina
No permit is required for standard air duct cleaning or dryer vent cleaning in Covina. Duct sealing that involves modifying or replacing ductwork may require a permit through the City of Covina Building Division; we handle the paperwork on jobs where it’s needed. Call (361) 326-5060 and we’ll confirm whether your specific job triggers a permit requirement.
We schedule most Covina appointments within 48 hours, with dispatch coordinated from our Los Angeles office. We do not promise same-day service because duct cleaning is a scheduled job that requires proper setup time and equipment loading; rushing it leads to missed connections and incomplete cleaning.
Most Covina HOAs do not regulate indoor duct cleaning or sealing, though a few planned communities in Covina Hills and South Hills require 24-hour notice for any contractor vehicle parking in shared driveways. We carry proof of insurance and background-check documentation for any HOA that requests it. Call (361) 326-5060 if you need us to coordinate with your property manager.
